如何运用Gdb对ARM板上的程序进行远程调试
在arm板上运行 gdbserver
[root@51Board usb]# ./gdbserver 192.168.0.29:1234 arm0702_8.out
Process arm0702_8.out created; pid = 228
从服务器中等待一个请求
这个是对qte程序的调试，先运行程序再调试进程号。在PC机上程序名称一样的。
// ./gdbserver 192.168.0.29:1234 --attach 545
说明：
这里的192.168.0.29是上位PC机的IP(这个应该于ARM板上的IP在一个网段内)
1234这里规定的端口号，等下要用到的，当然这个也可以用其他的端口号
Arm0702_8.out
上位PC机运行 arm-linux-gdb 调试程序
[root@zieckey collieryMainSrc02]# arm-linux-gdb arm0702_8.out

(gdb)
上位PC机连接到ARM板
[root@zieckey collieryMainSrc02]# arm-linux-gdb arm0702_8.out

(gdb) target remote 192.168.0.50:1234
Remote debugging using 192.168.0.50:1234
0x40001550 in ?? ()
这时ARM板上的信息应该是这样的：
[root@51Board usb]# ./gdbserver 192.168.0.29:1234 arm0702_8.out
Process arm0702_8.out created; pid = 228
Remote debugging from host 192.168.0.29
现在就已经建立其了PC机通ARM板山的连接了。
那么我们就可以像调试本地程序一样调试ARM板上程序。
例如：
(gdb) list
19 //#include "cmaininterfacewidget.h"
20 //#include "headers.h"
21
22 #include "cwidgetmanager.h"
23 #define _DEBUG_
24 #define _DEBUGCDatabase_
25
26 int main( int argc, char ** argv )
27 {
28 QApplication app( argc, argv );
(gdb) break 28
Breakpoint 1 at 0xf25c: file main.cpp, line 28.
(gdb) target remote 192.168.0.50:1234
Remote debugging using 192.168.0.50:1234

(gdb) quit
上面的那些错误是因为在ARM上指定路径有的库文件在PC上没有而引起的。
